FERDINAND MESSMER, OF ST. LOUIS, MISSOURI.

COOLING-COIL.

SPECIFICATIQN forming part of Letters Patent No. 682,634, dated September 17, 1901. Application filed May 15, 1961. Serial No. 60,384. (NomodeL) To otZZ whom it may concern.-

Be it known that I, FERDINAND ME'ssME'R, a citizen of the United States, residing at St. Louis, State of Missouri,have invented certain new and useful Improvementsin Cooling-Ooils,of which the following is a full,clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in cooling-coils; and it consists in the novel construction of coil more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a top plan of the device. Fig. 2 is aside elevation thereof. Fig. 3 is an end view with part of the coverplate removed, and Fig. 4 is a section on line 4 4 of Fig. 1.

The object of my invention is to construct a cooling-coil specially adapted for cooling beverages-such as beer, ale, and the like which generally leave a sediment or deposit in such coil while passing through the same.

The special purpose of the present invention is to construct a coil which may be readily taken apart for purposes of cleaning such sediment and any impurities which may from time to time accumulate therein. In detail the invention may be described as follows:

Referring to the drawings, 1 represents a series of metallic tubes inserted at their opposite ends into openings formed in suitable plates or heads 2 2, one end of each plate being provided with a hollow nozzle 3, having openings connected, respectively, with the end tubes of the series and with pipe-sections 4 4 by means of ordinary unions 5 5. The pipe-sections 4 4 are adapted to couple to ends of hose leading, respectively, to the vessel supplying the beverage and to the fancet delivering the same, it being understood that the present coil is placed into a suitable refrigerator or box, the ice being placed on top of the coil. By spacing the tubes suitable distances apart, as indicated, the cold air and small particles of ice and water have a chance to circulate freely around each tube and reduce the temperature of the beverage flowing therethrough. To form a continuous coil or circuitous passage from one pipesection 4 to the opposite section 4, I secure to each head or plate a cover-plate 2 2, a suitable rubber packing 6 being interposed between each pair of plates. The cover-plate has formed alongits inner face a series of concave pockets 7, each pocket spanning the division wall or metal separating any two consecutive openings formed in the plate 2, and thereby establishing communication between the adjacent ends of two contiguous tubes. The pockets of one cover-plate alternate in relative position with those of the opposite cover-plate, so that any tube of the series shall have one end brought into communication with the adjacent end of a tube on one side and the opposite end brought into communication with the adjacent end of a tube on the other side thereof, such connections making one continuous coil or passage from the inlet-pipe 4 to the outlet-pipe 4'.

While I have shown the inlet and outlet openings at diagonally opposite corners of the coil, it is obvious that by reducingor increasing the number of tubes by one the said openings could'be disposed along adjacent corners of the coil. 1 It is further obvious that minor details in the construction of the present device may be altered without departing from the nature or spirit of my invention. The heads extend a suitable distance beyond the general plane of the tubes to prevent large pieces of ice from hearing directly against the tubes and bending the same. It is apparent that by simply removing the cover-plates each tube may be readily cleaned or swabbed of any sediment which may have accumulatedtherein.

Having described my invention, what I claim is- Acooling-coil comprising a series of parallel tubes separated suitable distances apart, a plate at each end of the series into which the ends of the tubes are inserted, each plate having formed at one end thereof a hollow nozzle having two openings one of which connects with the end tubeof the series, and the other to a suitable pipe-section, a cover-plate for each of the aforesaid plates, each coverplate havinga series of concave pockets each spanning the ends of any two contiguous tubes, the pockets of one cover-plate alternating or breaking joint in relative position with the pockets of the opposite cover-plate, posed between each cover-plate and the plate 16 whereby any tube will be brought into comcarrying thetubes, substantially as set forth.

munication at one end with the adjacent end In testimony whereof I affix my signature of acontiguous tube on one side thereof, and in presence of two Witnesses.

5 at the other end with the adjacent end of a contiguous tube on the other side thereof, FERDINAND MESSMER' means for securing or coupling the cover- Witnesses: plates directly to the inner plates or heads, EMIL STAREK, and a suitable packing strip or layer inter- H. L. BELFRY.
